5. Unit Capacity (Display Code C)
Press the Extra Cycle button . Use this display to set the Unit
Capacity . This setting specifies the treatment capacity of the system
media . Enter the capacity of the media bed in grains of hardness
when configuring a softener system, or desired volume capacity
when configuring a filter system . This option setting is identified by
"C" in the upper left hand corner of the screen (or by "V' if volume
capacity for a filter) . The Unit Capacity parameter is only available if
the control type has been set to one of the metered options . Use the
Up and Down buttons to adjust the value as needed .

8. Safety Factor (Display Code SF)
Press the Extra Cycle button . Use this display to set the Safety
Factor . This setting specifies what percentage of the system
capacity will be held as a reserve . Since this value is expressed
as a percentage, any change to the unit capacity or feedwater
hardness that changes the calculated system capacity will result in a
corresponding change to the reserve volume . This option setting is
identified by "SF" in the upper left hand corner of the screen . Use the
UP and Down buttons to adjust the value from 0 to 50% as needed .
Figure 19
Range: 0-50%
9. Fixed Reserve Capacity (Display Code RC)
Press the Extra Cycle button . Use this display to set the Reserve
Capacity . This setting specifies a fixed volume that will be held as a
reserve . The reserve capacity cannot be set to a value greater than
one-half of the calculated system capacity . The reserve capacity is a
fixed volume and does not change if the unit capacity or feedwater
hardness are changed . This option setting is identified by "RC" in the
upper left-hand corner of the screen . Use the Up and Down buttons
to adjust the value as needed .
